What is driving the free-from trend – grain-free, gluten-free, lactose-free, sugar-free, fat-free, and so forth – and will it have legs? Which businesses are already tapping demand for free-from snacks and bakery products? We look at the alternatives the traditional snack ingredients, and who supplies them. Also, a peak into the manufacturing challenges in creating snacks and baking in the free-from category.

The unprecedented rise of free from: The free from sector was conceived for – and remains vital to – millions of consumers who deal with allergies, intolerances and related conditions, but today, the movement has evolved into something far more complex encompassing a host of consumer interests from health (free from sugar, fats, calories) to vegan (free from any animal products) to ethical (free from plastic)… Watch now

The demand for products with dual or multiple free-from labeling is growing: The rise of free from is throwing up unique challenges for manufacturers in that, often products that replace allergens can have an allergen classification themselves, like nuts to provide protein and fat content; or eggs or milk to bind ingredients in gluten free. We spoke to Verity Clifton, applications technologist at specialist ingredients company Thew Arnott, to find out more… Read

Grain-free may still be niche but it’s gaining traction among consumers who perceive it as the next step to better health. ‘Going completely grainless’ is becoming increasingly popular among consumers who are moving away from processed foods and incorporating natural ingredients, such as nuts, legumes and pulses, into their diets that boost their intake of proteins and minerals. The grain-free trend is an extension of the gluten-free trend, which is predicted to reach $4.35b by 2013 in the US, according to MicroMarketMonitor.

The unleavened bread that Roman Catholics use in the celebration of Mass must contain some gluten, even if only a trace amount, according to a new Vatican directive.

The directive…affirms an existing policy. But it may help to relieve some of the confusion surrounding church doctrine on gluten…The issue is especially urgent for people with celiac disease…or for those with other digestive conditions that make them vulnerable even to small amounts of gluten… “The confusion can be great when these ‘breads’ are advertised as gluten-free alongside what are described as gluten-free but are in fact low-gluten altar breads,” according to the Catholic Church in England and Wales. “The confusion can also be the cause of great upset both to those Catholics who are allergic to gluten and to those who minister to them.”

People with celiac disease cannot eat wheat, rye, or barley, which contain gluten proteins. If they do, the gluten leads to a toxic product that causes severe damage to the intestinal tract and other serious symptoms.

That is where the Benedictine Sisters of Perpetual Adoration of Clyde, Mo., come in. After a decade of work, they came up with a Vatican-approved wafer, using wheat starch and water. It contains just .001 percent gluten, an amount low enough for most celiac sufferers…They sell about 15,000 breads per week…”We believe Communion is the actual body of Christ and that’s the center point of our liturgy as Catholics — being able to receive Jesus.

What about other religions? My inside source at the Episcopal Grace Cathedral in San Francisco tells me that its services use

bread rather than wafers for communion, and almost always have a gluten-free alternative on hand (the bread is baked fresh for this purpose by the Bread Ministry!).

The purpose of doing this is “to make everyone feel welcome and included.”

FoodNavigator.com does occasional “special editions” in which they collect articles on particular topics from the perspective of their food-industry audience. This one is on food allergies and intolerances, about which remarkably little is known. If you are allergic or intolerant, the best you can do is hope for an accurate allergy test or do everything you can to avoid the food that triggers reactions. Good luck with that since allergies are hard to diagnose and allergenic ingredients sneak into a great many foods and are not always revealed on labels.

Food allergy is on the rise in many countries, but how many people are impacted in the US? We’ve collected some facts and figures from Food Allergy Research and Education (FARE), the world’s largest private source of funding for food allergy research; the CDC (Centers for Disease Control and Prevention); and NIAID, the lead institute at the National Institutes of Health conducting research on food allergy… Display [this site has basic statistics on prevalence and basic definitions of terms]

Soup-To-Nuts Podcast: Is low-FODMAP the new gluten-free?For the 45 million Americans who suffer from irritable bowel syndrome, identifying food that they can safely eat without triggering a flare up is a source of deep frustration that also could be a sizable market opportunity for innovative food and beverage companies that can provide an easy solution… Listen now

The Academy of Nutrition and Dietetics (formerly the American Dietetic Association) has just concluded its annual meeting and exhibition.

I was unable to attend but colleagues have been sending photos and giving me products or other objects collected at the exhibition. This exhibition is always worth a look. It typically features displays by food companies (Big Food and small) giving away samples of what I love to call “dietetic junk foods” in order to encourage dietitians to recommend them to clients.

Next: The National Confectioners Association has a handy guide to moderate candy consumption:

Then: Frito-Lay (owned by PepsiCo) ‘s new Gluten-Free chips.

Potato chips did not ever contain gluten, but never mind. They remind me of products offered during the low-carb craze a few years ago, like the ones I photographed when working on What to Eat in 2005.

My once-every-three-weeks column for the San Francisco Chronicle is set up as a Q and A. I don’t get many questions through the column, but the few that do come in are often quite challenging. This one is from a school chef wondering how to deal with kids who might be gluten intolerant – and whether gluten intolerance is becoming more common. Interesting questions! Here’s what I had to say about them. If you have questions about food and nutrition that you’d like me to answer, send them to food@sfchronicle.com (put Marion Nestle in the subject line).
